Abstract

In the mol-ecule of the title compound, C18H35N3P2, the methyl-pyridine-2,6-di-amine moiety is almost planar, with a maximum deviation of 0.0129 (9) Å for one of the amine N atoms. Whereas one of the P atoms is co-planar with this mean plane [deviation = 0.0158 (10) Å], the other P atom is considerably displaced out of the mean plane by 0.5882 (10) Å. In the crystal, no directional intermolecular interactions beyond van der Waals contacts could be identified.

Keywords: PNP pincer ligand; crystal structure; methylpyridine-2,6-diamine.
